<p>You can get the latest release of the SIP source code from
<a class="reference external" href="http://www.riverbankcomputing.com/software/sip/download">http://www.riverbankcomputing.com/software/sip/download</a>.</p>
<p>SIP is also included with all of the major Linux distributions.  However, it

<p>After unpacking the source package (either a <code class="docutils literal"><span class="pre">.tar.gz</span></code> or a <code class="docutils literal"><span class="pre">.zip</span></code> file
depending on your platform) you should then check for any <code class="docutils literal"><span class="pre">README</span></code> files
that relate to your platform.</p>
<p>Next you need to configure SIP by executing the <strong class="program">configure.py</strong> script.
For example:</p>
<div class="highlight-python"><div class="highlight"><pre>python configure.py
</pre></div>
</div>
<p>This assumes that the Python interpreter is on your path.  Something like the
following may be appropriate on Windows:</p>
<div class="highlight-python"><div class="highlight"><pre>c:\python34\python configure.py
</pre></div>
</div>
<p>If you have multiple versions of Python installed then make sure you use the
interpreter for which you wish SIP to generate bindings for.</p>

<p>Normally the <strong class="program">configure.py</strong> script uses SIP&#8217;s own build system to
create the Makefiles for the code generator and module.  This option causes
project files (<code class="docutils literal"><span class="pre">.pro</span></code> files) used by Qt&#8217;s <strong class="program">qmake</strong> program to be
generated instead.  <strong class="program">qmake</strong> should then be run to generate the
Makefiles.  This is particularly useful when cross-compiling.</p>
</dd></dl>

<p>The <strong class="program">configure.py</strong> script takes many other options that allows the
build system to be finely tuned.  These are of the form <code class="docutils literal"><span class="pre">name=value</span></code> or
<code class="docutils literal"><span class="pre">name+=value</span></code>.  The <code class="xref std std-option docutils literal"><span class="pre">--show-build-macros</span></code> option will display each supported <code class="docutils literal"><span class="pre">name</span></code>, although not
all are applicable to all platforms.</p>
<p>The <code class="docutils literal"><span class="pre">name=value</span></code> form means that <code class="docutils literal"><span class="pre">value</span></code> will replace the existing value of
<code class="docutils literal"><span class="pre">name</span></code>.</p>
<p>The <code class="docutils literal"><span class="pre">name+=value</span></code> form means that <code class="docutils literal"><span class="pre">value</span></code> will be appended to the existing
value of <code class="docutils literal"><span class="pre">name</span></code>.</p>
<p>For example, the following will disable support for C++ exceptions (and so
reduce the size of module binaries) when used with GCC:</p>
<div class="highlight-python"><div class="highlight"><pre>python configure.py CXXFLAGS+=-fno-exceptions
</pre></div>
</div>
<p>A pure Python module called <code class="docutils literal"><span class="pre">sipconfig.py</span></code> is generated by
<strong class="program">configure.py</strong>.  This defines each <code class="docutils literal"><span class="pre">name</span></code> and its corresponding
<code class="docutils literal"><span class="pre">value</span></code>.  Looking at it will give you a good idea of how the build system
uses the different options.  It is covered in detail in

<h3>Configuring for MinGW<a class="headerlink" href="#configuring-for-mingw" title="Permalink to this headline">¶</a></h3>

<h3>Configuring for the Borland C++ Compiler<a class="headerlink" href="#configuring-for-the-borland-c-compiler" title="Permalink to this headline">¶</a></h3>
<p>SIP, and the modules it generates, can be built with the free Borland C++
compiler.  You must use the <a class="reference internal" href="#cmdoption-configure.py-p"><code class="xref std std-option docutils literal"><span class="pre">--platform</span></code></a> command line

</div>
<p>You must also make sure you have a Borland-compatible version of the Python

Microsoft compiler) then you must convert the format of the Python library.
For example:</p>
<div class="highlight-python"><div class="highlight"><pre>coff2omf python34.lib python34_bcpp.lib

<span id="ref-configuration-files"></span><h2>Configuring with Configuration Files<a class="headerlink" href="#configuring-with-configuration-files" title="Permalink to this headline">¶</a></h2>
<p>The <strong class="program">configure.py</strong> script normally introspects the Python installation
of the interpreter running it in order to determine the names of the various
files and directories it needs.  This is fine for a native build of SIP but
isn&#8217;t appropriate when cross-compiling.  In this case it is possible to supply
a configuration file, specified using the
<a class="reference internal" href="#cmdoption-configure.py--configuration"><code class="xref std std-option docutils literal"><span class="pre">--configuration</span></code></a> option, which contains
definitions of all the required values.</p>
<p>The format of a configuration file is as follows:</p>
<ul class="simple">
<li>a configuration item is a single line containing a name/value pair separated
by <code class="docutils literal"><span class="pre">=</span></code></li>
<li>a value may include another value by embedding the name of that value
surrounded by <code class="docutils literal"><span class="pre">%(</span></code> and <code class="docutils literal"><span class="pre">)</span></code></li>
<li>comments begin with <code class="docutils literal"><span class="pre">#</span></code> and continue to the end of the line</li>
<li>blank lines are ignored.</li>
</ul>
<p><strong class="program">configure.py</strong> provides the following preset values for a
configuration:</p>
<dl class="docutils">

<dd>is the major version number of the target Python installation.</dd>
<dt><code class="docutils literal"><span class="pre">py_minor</span></code></dt>
<dd>is the minor version number of the target Python installation.</dd>
<dt><code class="docutils literal"><span class="pre">sysroot</span></code></dt>
